Abstract
Provided is a novel spinal fixation system that includes a novel multi-planar taper lock screw for connecting a connecting rod to bone as well as a novel locking device and a novel unlocking device, each being configured to selectively partially lock or fully the novel screw of the system. The screw is capable of multi-directional articulation while the connecting rod position can remain stable and aligned as needed. After the screw had been articulated and properly positioned, it can be locked such that the screw and the connecting rod will remain in relative position to the bone. The screw is configured for easy insertion and connection as well as easy removal and disconnection from the connecting rod. A method of fixing bones or bone fragments using the novel system is also provided.
